The Eller Beck is a small river in North Yorkshire, England, that flows through the town of Skipton and is a tributary of the River Aire. Its channel was heavily modified to supply water to mills in the 18th and 19th centuries, and although all the mills have closed, the water now supplies power to the National Grid, generated by a turbine at High Corn Mill. The beck flows through several underground culverts in Skipton that contribute to the flood risk. To alleviate flooding in Skipton town centre, a scheme involving two flood water storage reservoirs was designed and eventually completed in 2017.
